@Paul: do you mean this one?

It sure is stylish, the one aspect I didn't mention. I never saw one of these in real life but expect it to be heavy.
As far as design vs. weight is concerned: I can understand the tendency towards using H-frames but these are one of the causes of weight.
Boxes can be lighter when they're constructed using monocoque construction using plywood, epoxy and possibly a little fibre. I made a box years and years ago and remember it to be very light. It was decomissioned for reasons I dont't recall.
I don't know when I'll start construction. I just oiled the wood on the one I currently use and it looks nice. It's a bit like a marriage after years and years: the new ones look attractive and are a bit lighter but you're not prepared to let go of the one around
